Power Supply Connection
V-470/V-474A v2 series time zone displays are manufactured with universal mains power
supplies enabling operation at voltages from 100 to 240V ac 50/60Hz without adjustment.
Units for surface or flush mounting applications have an IEC mains socket located in the
external interface connector module and are supplied with a 2m mains cable preterminated
with either a UK, European, US or Australian style mains plug. The external interface
connector module may be found recessed into the rear of the clock as shown in appendix A.
Units for single or double sided ceiling suspension mounting applications are supplied with
a 3m unterminated captive mains cable (units for supply to the USA or Canada are supplied
with a 3m captive mains cable preterminated with a US style moulded plug).
A connection to the earth line must be made to ensure safe operation and compliance
with EMC regulations.
To ensure conformance with EN60950:
(A)
For installations where the V-470/V-474A v2 clock is to be permanently connected
into the mains power circuit, a readily accessible disconnect device should be
incorporated in the fixed wiring.
(B)
For installations where the V-470/V-474A v2 clock is to be plugged into the mains
power circuit, a socketed outlet should be installed near the equipment and should be
easily accessible.
All installation work should be performed in accordance with current Building
Regulations and the Sixteenth Edition of the IEE Wiring Regulations, or equivalent local
standard.
When time zone displays are used as stand-alone units, an internal Lithium battery will
maintain the internal time count if the mains supply is interrupted. In normal operation, this
battery should have a service life of greater than 10 years.
The power supply is fitted with an internal fuse. In case of fault the fuse should only be
replaced with a fuse of the same rating, by a suitably qualified engineer after disconnection
from the mains power supply and correction of the fault condition.
Synchronisation Signal Connection
A six way terminal block is located on the rear panel of the clock to enable the connection of
synchronisation signals, a GPS receiver system or a radio time code receiver. Details of the
connections for various signal configurations are detailed in appendix A. Please refer to
chapter 6 for information on synchronisation setup.
The mains power supply must be disconnected when making connections to external
signals.
Clocks supplied for ceiling suspension are supplied with a 6 way cable to enable connection
of external synchronisation signals.

Operating and Installation Instructions
GPS Synchronisation
The V-488GPS receiver system is designed to be automatically synchronised to time
signals transmitted from the Global Positioning System (GPS) navigation network. The GPS
constellation consists of 28 operational satellites, operating in 12 hour orbits at an altitude of
20,200km.
The V-488GPS receiver has been designed for simple installation and operation by the
end-user, requiring only a 4 wire interconnection to the V-470A/V-474A v2 series time zone
display. When synchronised to a V-488GPS receiver system the V-470A/V-474A v2 series time
zone display timebase is maintained within 50uS of UTC.
Advantages of V-488GPS time synchronisation:
•
Very accurate synchronisation
•
Can be used anywhere in the world
•
Better resistance to EM interference
Disadvantages of GPS time synchronisation:
•
Antenna needs to be mounted externally with a clear view of 75% of the sky.
The V-488GPS Antenna/receiver module
The V-488GPS synchronisation system is housed in a single IP66 rated case containing an
advanced combined Sony active antenna and 12 channel parallel GPS receiver module and a
microprocessor based communications interface.
The system is supplied complete with a post mounting clamp to enable the unit to be fixed
to a suitable horizontal or vertical post of up to 2cm diameter. The antenna should be
mounted on the roof of a building or under a suitable skylight.
The reception gain pattern is designed for full, upper hemispherical coverage with the gain
diminishing at low elevations. This cross-section is consistent through 360 degrees and so
the 3 dimensional gain pattern is a symmetrical spheroid surface.
Installation
To ensure ease of operation and to remove the possibility of operator error, the V-488GPS
system is designed to self initialise.
Ensure that the V-470A/V-474A v2 series time zone display is disconnected from the mains
power supply when making connections to the V-488GPS receiver system.
1
Install the V-488GPS unit horizontally using the post mounting kit provided. Ensure that
the unit has a clear view of at least 75% of the sky. If the sky view is reduced the
interval between ‘switch-on’ and system time synchronisation will be considerably
increased.
2
The V-488GPS should be connected to the V-470A/V-474A v2 series time zone display
using the captive 25 metre four core cable supplied. For distances of up to 50 metres
the length can be extended by adding an additional length of 7/0.2 cable. For greater
distances, up to a maximum of 200m, 16/0.2 (0.5mm2) cable should be used. The
cable should be connected to the 6 way terminal block on the rear of the V-470A/V-474A v2
series time zone display as shown in figure 3. The cable screen should be connected
to the EMC ground connection on the 6 way terminal block.

Once the power has been applied the receiver will automatically begin to search the
sky for all available satellites. During this process the green LED inside the V-488GPS
unit will flash. After three satellites have been acquired the green LED will stop
flashing and become constantly illuminated, indicating that a precise date and time
has been calculated from the satellite data transmissions. From a ‘cold’ start this
process will typically take less than 10 minutes.
5
Ensure that the V-470A/V-474A v2 series time zone display is configured to synchronise
from the GPS signal by following the procedure on page 6-1.
Once the green LED has illuminated the synchronising time signals are transmitted from the
receiver/decoder module to the V-470A/V-474A v2 series time zone display. The V-470A/V-474A v2
series time zone display should lock in and display the correct time within 5 minutes.
MSF and DCF synchronisation
MSF and DCF are the two most widely used radio time code signals. The DCF signal is
derived from the atomic clocks at the Physics Institute of Brunswick and transmitted at a
frequency of 77.5KHz from Manflingen, near Frankfurt in Germany. The MSF signal is
referenced to the Caesium Beam Oscillators at the National Physical Laboratory and
transmitted on a frequency of 60KHz from Anthorn in the United Kingdom.
Under normal circumstances the DCF signal provides reliable operation at distances of up to
1500km, MSF signals are normally usable up to 1000km from the transmitter. Greater
operating ranges are possible at night.
When synchronised to MSF or DCF using a 484 radio receiver the V-470A/V-474A v2 series time
zone display timebase is maintained within 30mS of UTC.
Advantages of MSF and DCF time synchronisation:
•
Lower purchase cost than GPS
•
Can sometimes be installed internally.
Disadvantages of MSF and DCF time synchronisation:
•
Can be difficult to find good location for signal reception.
•
Suffers greatly from EM interference - Avoid locating near computers, electronic
equipment, fluorescent lighting, lift equipment, metal girders, reinforced concrete
walls and all other sources of electrical noise.
•
MSF is off-air for maintenance on the second Thursday of every March, June,
September and December. MSF status can be checked by telephoning 020 8943 6493.

V-470A/V-474A v2 Series Time Zone Displays
Operating and Installation Instructions
Installation
The V-484 series time code receiver should be mounted:
•
At least 2.5 metres from the V-470A/V-474A v2 series time zone display.
•
At greatest practical distance from:
Other electronic equipment including computers, fluorescent lights and signs, metal
girders, reinforced concrete walls and any other sources of electrical noise.
•
On the side of the building nearest Anthorn (MSF) or Frankfurt (DCF).
•
Preferably on the outside of the building (V-484.02 and V-484.03 only) as high as possible.
The case is weatherproof to IP65 (V-484.02 and V-484.03 only) but it is preferable to
provide some protection from direct rain.
•
With the cable entry on the lower face of the case. (V-484.02 and V-484.03 only)
The antenna is supplied with 3 metres of two core cable, if a longer cable distance is
required Appendix B should be consulted for suitable cable specifications. The maximum
distance between the 484 radio receiver and the V-470A/V-474A v2 series time zone display is
200m.
If a screened cable is used, the cable screen should be connected to the EMC grounding
terminal on the rear of the V-470A/V-474A v2 series time zone display.
Alignment
The V-484.02 (MSF) and V-484.03 (DCF) radio receivers have dual ferrite antennas, which
normally permit location regardless of orientation to the transmitter. The receiver is
mounted by means of four fixing holes in the rear surface which are accessed after removing
the front cover. The four mounting holes are located outside of the central sealed
compartment.
The V-484.06 (MSF) and V-484.07 (DCF) receivers have a single antenna element and are
supplied with an adjustable mounting bracket so that the installer can ensure that the
orientation of the longest face of the receiver is at 90o to the direction of the transmitter.
The front cover of the V-484.02 and V-484.03 receivers may be removed to enable the indicator
LED to be viewed. The indicator LED on the V-484.06 and V-484.07 receiver is located on the
front face of the unit.
The alignment of the receiver is correct when the LED flashes on/off once per second.
Signal reception
In good conditions the V-470A/V-474A v2 series time zone display will take three minutes to
synchronise with the transmitted time code from either DCF or MSF. When the V-470A/V-474A v2
series time zone display is ‘locked’ to the transmitted signal, the colon LEDs located
between the hours and minutes displays on each time zone are illuminated continuously.
During periods of signal failure or signal corruption the clock will maintain timekeeping
using its internal quartz crystal oscillator.
w482 Time Code Synchronisation
In large installations, multiple V-470A/V-474A v2 series time zone displays may be controlled via
a Timelord master clock. The master clock provides centralised control for a maximum
of 50 displays using the w482 time code system.
Issue 1.1h
6-5
V-470A/V-474A v2 Series Time Zone Displays
Operating and Installation Instructions
The w482 Time Code Signal
The w482 signal was developed for controlling electronic clocks, using a single cable pair
data interconnection, in electrically noisy environments. A principle advantage of w482 is the
ability to provide time information in any one of fifteen different synchronised time zones.
All fifteen time zones can be individually configured on the master clock to provide
automatic seasonal time change correction.
The w482 signal is transmitted at 4-24v amplitude at a rate of 50 bits per second. The
signal is virtually immune to electromagnetic interference. One Timelord master clock
can control up to fifty V-470A/V-474A v2 series time zone displays located up to 1km from the
master clock using a simple, non-critical cable pair.
Installation
If your V-470A/V-474A v2 series time zone display has been supplied with a master clock, it will
already be programmed so that the individual time zones are set to display the correct w482
zones, (i.e. - if the master clock is setup so the Zone 1 is New York time, then the zone
labelled ‘New York’ on the V-470/V-474A time zone display should be set to zone 1 or Z1).
If the V-470A/V-474A v2 series time zone display is to be used with an existing system, the zones
should be set to correspond with the zone settings in the master clock. Please refer to the
diagram below for further details of this setting procedure.
Please refer to Appendix A for connection information and Appendix B for recommended
cable specifications.
Please note that the ‘time setting’ & ‘location’ options normally found in the function
programming menu are not present when the unit is programmed for w482 time code
synchronisation.

8 - Ethernet Network Connection (N/NIL units only)
V-470/V-474N/NIL series time zone displays are designed to synchronise to a remote NTP
(Network Time Protocol) time server across a TCP/IP computer network. The units are fitted
with a dual speed 10/100Base-T RJ45 Ethernet interface and may be connected either to a
dedicated 10Base-T or 100Base-T port or to a switchable 10/100Base-T port on your network.
Upon initial installation, the unit IP address, subnet mask, gateway and NTP time server IP
address should be programmed as detailed in the setup procedure below. Alternatively, the
DHCP setting may be selected to enable the unit to obtain it’s IP address, subnet mask and
gateway settings automatically.
With the unit connected to your computer network, settings may be remotely monitored and
adjusted via the web interface. Additionally, if your unit has illuminated locations (NIL
versions only), the displayed location text may be remotely adjusted using the web interface.
Initial Setup Procedure
Before connecting the V-470/V-474N/NIL unit to your computer network, the following procedure
should be performed using the setting switches located on the right hand rear of the display.

Appendix B - Cable Specifications
V-470A/V-474A v2 -> V-488GPS interconnection
The V-488GPS Receiver system is supplied with 25 metres of four core 7/0.2 (0.22mm2)
screened cable. The cable screen should be grounded at the V-470A/V-474A v2 end by means of
the EMC rear grounding terminal.
For distances of up to 50 metres the length can be extended by adding an additional length
of 7/0.2 cable. For greater distances, up to a maximum of 200m, 16/0.2 (0.5mm2) cable
should be used.
V-470A/V-474A v2 -> V-484 MSF and DCF radio receiver interconnection
The V-484 series radio receiver is supplied with a 3m long unscreened cable as standard. The
cable length may be extended to 10m using unscreened cable, RS 528-2235 - 22 awg or
equivalent. In areas of high electrical noise a screened twisted pair should be used. The
cable screen should be grounded at the V-470A/V-474A v2 end only.
The cable length may be extended to 200m using a screened twisted pair cable, RS 5281917 - 22 awg or equivalent. (UL style 2092, Alpha 2401). For screened LSOH (Low Smoke
Zero Halogen) applications RS 528-2308 (two pairs 7/0.25 - 22 awg) may be used. Equivalent
to UL style 2493.
V-470A/V-474A v2 -> Timelord master clock interconnection
The w482 time code transmitted from a Timelord series master clock is designed to have
considerable immunity to external electrical interference and screened cable is only required
in areas of high electrical noise.
Normal installations may use standard mains cable. (e.g. twin 1.5mm2) The size of the cable
depends on the overall cable length, the number of clocks and their spacing on the cable.
The use of twin 1.5mm2 cable will be adequate for installations of up to 50 V-470A/V-474A v2
using up to 1km of cable.
Unscreened data cables should not be run in proximity to power cables supplying
fluorescent lighting or other sources of electrical noise. In areas of high electrical noise a
screened twisted pair should be used. The cable screen should be grounded at the
Timelord end only by means of the rear grounding terminal. A suitable screened cable is RS 5282241, (twin 16/0.254 - 18 awg) equivalent to Alpha 2421, BICC H8093, UL style 2092 which is
adequate for a spur controlling 25 clocks over a 1km cable run or a greater number of clocks
over a shorter distance.
For a Cat 5 installation, (24 awg) a single pair can be used to connect up to 10 V-470A/V-474A v2
series time zone displays at a distance of up to 250m. For further distances or greater
numbers of clocks, additional cores should be paired together, lowering the cable resistance.
If in doubt one should always consider the use of the next heavier gauge cable as this
invariably increases system integrity at minimal additional system cost and allows for future
system expansion.
All installation work should be performed in accordance with the Sixteenth Edition of the IEE
Wiring Regulations, or equivalent local regulations.

Appendix D - Frequently Asked Questions
How can I tell if the V-470A/V-474A v2 series time zone display has synchronised to
my chosen synchronisation time source?
When the V-470A/V-474A v2 series time zone display is synchronised (or programmed for standalone operation), the colon LEDs between the hours and minutes display of the left-hand
time zone will illuminate continually. If the unit is unsynchronised, the colon LEDs between
the hours and minutes display of the left-hand time zone will flash.
Why are some or all of the times shown on the V-470A/V-474A v2 series time zone
display not correct, even though the unit is synchronised?
Check that the location is set correctly for each zone - please refer to chapter 4 for further
details.
Why have some or all of the zones on the V-470A/V-474A v2 series time zone display
not performed seasonal time changes?
Check that the location is set correctly for each zone - please refer to chapter 4 for further
details.
If the unit is unsynchronised, check the date is correctly programmed - please refer to
chapter 5 for further details.
Will the V-488GPS receiver system work internally?
The V-488GPS receiver system is designed for external mounting. We would recommend
positioning the system on the roof of the building with a clear view of at least 75% of the sky
- please refer to chapter 6 for further information.
Can I extend the cable supplied with the V-488GPS receiver system?
The system is supplied with 25 metres of four-core screened cable for connection to a V-470A/
V-474A v2 series time zone display. This cable length may be increased up to a maximum of
50 metres using a similar type of cable or up to a maximum of 200 metres using a heavier
gauge cable - please refer to chapter 6 and appendix B for further information.
Why will the V-470A/V-474A v2 series time zone display not synchronise to the MSF or
DCF radio time code signal?
Under normal circumstances the MSF signal provides reliable operation at distances of up to
1000km from Anthorn in the United Kingdom. The DCF signal is normally usable up to
1500km from Frankfurt in Germany.
In good conditions the V-470A/V-474A v2 series time zone display, when used with a V-484 series
radio time code receiver should synchronise to MSF or DCF within 3 minutes. During this
period, the ‘code’ LED housed inside the 484 series radio time code receiver should flash
once per second.
However, MSF and DCF suffer greatly from electromagnetic interference which can cause the
V-470A/V-474A v2 series time zone display not to synchronise. In this instance, the ‘code’ LED
housed inside the V-484 series radio time code receiver may flash erratically. To minimise
interference problems, we would recommend mounting the 484 series radio time code
receiver away from any computer or electronic equipment, fluorescent lighting, lift
equipment, metal girders, reinforced concrete walls or any other sources of electrical noise.

Will the V-484 series radio time code receiver work internally?
The V-484.02 MSF and V-484.03 DCF radio time code receivers are suitable for either internal or
protected external mounting. For reliable operation, we would recommend mounting these
units externally if possible.
The V-484.06 MSF and V-484.07 DCF radio time code receivers are suitable for internal use only please refer to chapter 6 for further information.
Can I extend the cable to my V-484 series radio time code receiver?
The cable connection to a V-484 series radio time code receiver may be extended up to a
maximum of 10m using a similar specification cable. This connection may be extended up to
a maximum of 200 metres using a screened twisted pair cable as specified in appendix B.
How do I change the locations on a single sided (.SS) and double sided (.DS)
ceiling suspended AIL type time zone display?
Ceiling suspended AIL type time zone displays are supplied with an additional data cable
and a serial cable which are used to configure the user programmable location legends.
Please connect the PC Update cable to the Serial cable are detailed below - please refer to
chapter 7 for further information regarding programming location legends.
